I have fill a ballon with water. The balloon becomes big for its elasticity. So a potential energy is been stored on the surface of the baloon that is giving pressure on the water inside. Now I need to find that pressure. There is a way to find it using bulk modulus but the problem is I don't know the bulk modulus for the rubber of that ballon.
So I am finding a way to find the pressure.
Also I'm confused if I mesure the weight of the water inside and consider that as force and measure the current area of the ballon and divide then what will be the value? Is that will be the pressure of the ballon! I'm really confused.
